"1. WHAT ARE LEAF MINERS?
Leaf miners are any larvae that start as eggs which are located on the underside of the leaves and as soon as they hatch, these yellowish white worm-like insects go into the leaves of your cannabis plant, eating the plant tissue and leaving a trail behind.Leaf miners are not actually a specific species of bug. It is a term used for the larvae of any bug (moths, flies, and beetles) that lays eggs on your plant’s leaves. "

Leaf damage causes low yields.
When the females dig to lay eggs, plants secrete a sap that attracts ants and flies, thus inviting more infestations and problems.
There are many species of leaf miners, and an expert can distinguish between species by the characteristic appearance of the tunnels which evolved to provide them more protection than the surface of leaves.
Females implant one egg at a time close together. Species vary in fecundity. Some produce up to 350 eggs each. Eggs hatch in two to six days, and larvae begin tunneling. Eventually they become pupae, either dropping to the ground or remaining in the leaf, (depending on species).
The pupae develop into adults and the cycle repeats. Expect two to six generations per year outdoors, but indoors a single generation can take as little as a month, and they reproduce year-round."
